In this study, A356.0 alloys were reinforced with varied percentage of Graphite by liquid metallurgy route, heat treated (T6) and tested for microstructure, mechanical properties. Wear tests were conducted using Pin-on-Disc apparatus at a constant sliding velocity of 1m/s and pressure of 0.35 MPa. Microstructure revealed uniform distribution of reinforcement in the matrix resulting in improved mechanical properties and wear resistance compared to un-reinforced material. The ceramic reinforced alloys were found to have improvement in mechanical properties and wear resistance compared to unreinforced alloy which may be attributed to the uniform distribution and improved bonding of reinforcement in the matrix.
